Casa Performance 10% reinforced cush drive spring for Lambretta S1 S2 S3 GP

NEW FROM CASA PERFORMANCE!  10% reinforced cush drive spring for Lambretta S1 S2 S3 (Special, TV, SX) GP Serveta. We were unsatisfied with the majority of the cush-drive springs available on the market, so we decided to make our own version in Italy, using only the best materials. We retained the original Innocenti dimensons, so the cush drive springs can easily replace the original one without any modifications required. We increased the resistance of the spring by 10% making it better suited to any type of tuned engine and we fit these as standard to all of our CP engine builds. Perfect if used with the Casa Performance sprocket assembly code X176 or X176a if you already use a CasaCase.
